We’re not quite sure just what the heck Lady GaGa is playing here, but it looks like she’s got a keytar slash bass slash MPC GaGatar in the Haus.

You can see Lady Gaga’s keytar thing in action in her video for Telephone & Dance in the Dark, below, unless it gets yanked by the YouTube police.

Check it out and let me know what you think of the GaGatar. And if you know anything more about it, leave a comment!
